Toallwhomitmayconcem: l Be it known that I, J Arms OFBIEL, of Brook; lyn, in the county of Kings andState of New York, have invented an Improved Composition for Artificial Stone; and the following is declared to be a correct description thereof.

The compounds in. which tar forms a part are liable to soften in-warm weather and mixtures of lime and sand with stone, or ordinary hydraulic cement, do not resist the action of frost, especially 0f soda 01"] I :2 oxjd gmn. 'ganese will form a cement that'will harden and.

be'vfi y'tough, strong, and water-proof, and at the same time there will not be disintegration or deliquescence. I make use of Portland cement and black oxide of mananese 1n the propofi1o"n of flow 1 a ousan pafis oi the former to one hundred and sixteen parts'of thelatter; these are to be mixed with about five thousand parts of silex or cla These are to be mixed intimately t in a Ey sfii and then mixed into a plastic state by the additionof silicate of soda or water-glass.

This composition may als'o contain about one hundred parts of oxideof silicum mixed with the same. Other m r1a aving ne same ingredients as Portland-cement may take the place of the said cement in the said compound. Where itis desired -to cause this compound to harden with greater rapidity a solution of chloride of calcium or chloride of iron may be spreadu' p"o'n e sur ace 0 to its place.v v p a When this composition cement is to be applied e cemen after it has been laid -to roadways, sidewalks, or floors, broken stones or chips are to be added many desired propor-. .tion so long as the said plastic cement is suf- "flcient to-fill the interstices and'form aperfect ibond for said chips broken'stones.
